A precoated metal plate for heavy forming use comprising a metal plate having on its surface a coating which is prepared by applying an aqueous composition consisting essentially of a binder component (A) and hard inorganic microparticles (B) and which is 0.05 to 5 .mu. thickness, the binder component (A) being an aqueous resin or a combination of aqueous resin and a water-soluble chromium compound containing 30 to 90% by weight of hexavalent chromium, the microparticles having Mohs' hardness of 3 to 9 and an average grain diameter of 0.1 to 20 .mu., and the coating being characterized by having a percentage of horizontal sectional area of the inorganic microparticles protruded beyond the film surface of said binder component at the film surface of 5% or more. The coated metal plate is specifically useful for heavy forming purpose.
